The portions of the strip lie close to the surfaces of the flange so that the cap may be applied to the bottle neck by the usual capping mechanism. After the strip or extension has been folded to extend parallel with the flange the flange and strip will be crimped as' shown more particularly in Figs. 5, 6 and 'l of the drawings. The inner edge of the strip 5 will terminate on a line or plane with the weakened line! of projections or indentations so that a portion of the flange maybe torn as will be described to release the cap from the bottle mouth.

. As has been stated the cap is of such a formation that it may be applied to the bottle mouth by the usual capping mechanism and when it is desired to remove the cap the person engages the free end i 2 of that portion of the strip 5, which extends exteriorly of the flange, and bends the same outwardly to provide a finger grip, so that the strip may be pulled as shown more particularly in Fig. 7 of the drawings and this pull on the tear strip will tear the flange along the weak-- 'ened line 9 of perforations or indentations and remove a suflicient length of the flange to permit the cap to be readily removed from the bottle mouth. It will thus be seen that I have provided a novel construction wherein the'cap may be removed without the use of 'a' cap remover or other implement. This is of particular advantage for a person desiring to consume the contents of the bottle may remove the cap without unnecessary delay as would be caused in looking for and applying the ordinary cap remover. The strip provides a finger-engaging portion exteriorly of the flange, which may be so pulled as to cause the interior portion to tear the flange'outwardly to remove a portion thereof as shown and described.

In Figs. 8 to 15 inclusive of the drawings, I have illustrated a slightly modified form of my invention wherein the tear strip is formed as a separate part from the cap, as distinguished from the integral formation disclosed in Figs. 1 to 7 inclusive. In this modified form of the invention the top portion of the cap is shown at H and the flange portion at I4. The flange with the tear strip will be crimped, as shown at. I, more particularly in Figs. 12 to 15 inclusive and a cork insert I will be positioned within the, cap, as shown more particularly in Fig. of the drawings. An opening ll is formed in the cap flange and extends inwardly to a point beneath the cork insert I. A weakened line l8, formed by perforations or indentations, extendscircumferentially for a portion of the flange from the inner end of the opening H, as quite clearly shown in Fig, 9 of the drawings, and this weakened line will be at a point just inwardly of the inner face of the cork insert it.

The tear strip is indicated at I! and at one end is provided with an extension 20. As shown .the flange. The innerfledgejof the strip will be can plane withthe weakened line of perforations or indentations l8. After the strip has been thus positioned it will be crimped with the flange, as

shown more particularly at I! in Figs. 12 to 15 inclusive of the drawings. The portions of the tear strip will lie so close'to the flange that the cap may be applied to the bottle mouth by the usual form of capping mechanism and the cork insert 16 will engage the inner face of the extension 20 to aid in holding the strip in position, the end of the extension being positioned between the outer edge of the insert and the inner face of the flange.

When it is desired to remove the cap from the bottle mouth the person engages the free end 23 of the tear strip or that portion 22 extending parallel with the exterior face of the flange and bends the same outwardly to a position that a secure finger grip is provided. Then a pull is given to draw the portion 22 outwardly, as shown more particularly in Fig. 15 of the drawings, and

this pulling action tears away a portion of the flange along the weakened line I8 for a sufficient a portion extending parallel with the interior of the flange and a portion extending parallel with the exterior thereof.

A bottle cap of the character described including top and flange portions, the flange having an opening from its free edge and terminating at a weakened line extending circumferentially of a portion of the flange, and a tear strip extending through the flange opening with a portion extending parallel with the interior of the flange and a portion extending parallel with the exterior thereof.

A bottle cap of the character described including top and flange portions, the flange having an opening from its free edge and terminating at a weakened line extending circumferentially of a portion of the flange, and a tear strip extending through the flange opening with a portion extending parallel with the interior of the flange and a portion extending parallel with the exterior thereof, the inner longitudinal edge of the tear strip being on a plane with the weakened line of the flange portion.

4. A bottle cap of the character described including top and flange portions, the flange having an opening from its free edge, and 'a strip formed integral with the flange and adapted to be folded to extend through the opening with a portion extending parallel with the inner face of the flange and a portion extending parallel with the outer face thereof.
